The PGP Encryption Server and PGP Encryption Desktop can search key servers using LDAP (389), LDAPS (636) or USP (PGP Universal Services Protocol on port 443).

Key servers are configured on the Keys/Keyservers page of the PGP Encryption Server administration console.

PGP Encryption Desktop managed by PGP Encryption Server will use the PGP server as a proxy to search for keys on its behalf.

Key servers can also be added directly to the PGP Encryption Desktop client if needed.

Currently a request is open to use Secure OpenPGP HTTP Keyserver Protocol (HKPS) or OpenPGP Web Key Directory (WKD).

The PGP Encryption Server provides several options for accessing the public keys of external users:

1. Web Email Protection allows external users to upload their PGP key or S/MIME certificate. Encryption Management Server will use these keys or certificates when sending encrypted mail to external users.
2. The Verified Directory service allows external users to upload their PGP key and search for the public keys of internal users.
3. External users can upload their PGP key to the PGP Global Directory. Encryption Management Server will search the PGP Global Directory when sending encrypted mail to external users.

If you would like to have HKPS or WKD, please reach out to Symantec Encryption Support for further guidance.
